OFFICE Be it known that I ,dhx mxo Baomvraozix',l a citizen" of 'thfe .UnitedStatesjlre'sidiiig at Chicago, in the county of Cook lidfState of illinois, have invented certain new'and usey ful `Improvements inafCimibination Rule, Bevel-Square`,Gage, and Compass, of which the following is a description..

My invention relates to combination tools and particularly tov a 'combination Vtool adapted for the use of carpenters or murhinists. A

The objet-.t of my invention is to provide a tool of the class mentioned adaptedy for various uae's in measuring and ina'rkingoat the work..4

A further object-ot `myfinventiouis to provide a'tool of theclass' under consideration `which'.shall-be of simple eoustruetion, of lowcost 4to manufacture and diirable. i i (.)ther objects -will appear:hereinafter.

With .thesel objects in view mvinvention eoiisists renerallyrin a' paix-"foi"l graduated blades w iieh'are both pivotally uml slidably connected whereby'the .device muy be used as an extension,"rule, u square or a bevel, and equij'ipedw-ith suitable pointand projections whereby the sameis adapted' l'or ostias a gageor a compass.

Mv invention', furtlierveoimistn in various details of construction`and arrangements of parts all as will be fully deaeribed hereinut'ter and particularly pointed out in tho Claims.

M y. invention will be more readily under- Qtood by reference t0 the nelolupzlnylng drawings forming u part 'of this xpeiuliralion um in which-f 4 [figure l is a plan view of thi` tootvln. flora-d position, Fig. 2 is a side elevation .ot the same, Fig. this a lan .view ot' the drvirr with the bladesisligiitly extended longitir diuallj'. l"ig .t is a similar view with the blades awan r to full extended punition.

The. ends of-tho blades adjacentI the sind t2' are preferably rounded as indicated at ,7.

`.'Xdjaeent. the opposite ond of the blade B fromthe'rounded end is a depending, transversely dispersed tongue 8 which projectol through the slot 1 in the bladeA and which isl Provided with a lhaipened or pionieri em t).

When used as a gage the stud 6 a uts the edge of the work, as shown,in F ig. 9 and the blade'B is'adjusted until the marking point is at the proper distance from the stud, yafter which the nut is tightened andthe ters Patent is:

1. In .a' device of the classl described, a

tudinally disposed slot, a stud extending through one of said blades adjacent the end' `thereof, one end ofI said stud projecting below theblade and pointed and the other end projecting upwardly andt-hreaded, said threaded end extending through-the slot in the other blade, a thumb nut threaded on said upwardly projecting end, and a pointed l tongue projecting downwardly from the op- .i

posite' blade from that to which the stud is secured and extending through the slot in the latter .substantially as described.

2. Inn a device of the elassvdeseribed', an upper blade and a lower blade eaeh of said blad being provided with a longitudinally disposed slot, a-stud Fixed in the lower blade adjacent' oneend thereof and provided with a depending pointed end, a reduced upwardly extending stem on .said stud project ing through the -slot in the upper blade, a binding nut threaded on said stern, a down` wardly extending tongue adjacent the end of the upper blade normally remote from said binding nut and projecting through the slot in the lower blade, said tongue being of greater width than said slot and reduced in width at its upper end to snugly lit the same, theslotlin the lower blade being provided with a widened portion to permit passage of said tongue and an upwardly extending earon the end of the upper blade,
